Plant Grow Light Lights Illuminate The Process Of Modern Agriculture

Modern agricultural is physical technology and agricultural production of organic combined, is using has biological effect of electric, and sound, and light, and magnetic, and hot, and nuclear, physical factor control flora and fauna of life environment and growth development, prompted traditional agricultural gradually out on chemical pesticide, and chemical fertilizers, and antibiotics, chemicals of rely on and natural environment of bound, eventually gets quality, and high yield, and nontoxic agricultural of environment regulation type agricultural.

"Light, temperature, water, fertilizer and air" are the main environmental factors required for plant growth, the "light" of these factors first. "Modern agriculture plant factory is one of the main features of intelligent control of artificial light sources and light environment" has become a general consensus in the industry. In recent years, with increasing atmospheric pollution, declining atmospheric transparency coefficient, resulting in decreasing of solar radiation reaching the surface. Fewer and fewer plants to receive access to the sun light, it is difficult to meet the needs of normal growth and development. In addition, global warming causes more extreme weather, plants suffer continuous rain increased frequency of sunless weather, plants, solar energy is becoming increasingly unreliable. In the South-eastern coastal areas, the ground receives light decreasing trend of more dramatic than the downward trend in the country as a whole. Using suitable artificial lighting is key to the development and application of plant factory. Therefore, the artificial light source products based on plant growth and reasonable demands and its intelligent optical control technology research and development and application of plant factory and its cultivation method of innovation is the core content and plant factory hallmark.

Light environment is essential to plant growth an important physical factor, light control, control of plant morphogenesis is an important technology in the field of protected cultivation.

Influence of spectral ranges on Plant Physiology:

280nm to 315nm little effect on morphological and physiological processes

315 nm~ 420nm chlorophyll absorbs less effect of photoperiod effect prevents stem elongation

420 nm~ 500nm (blue) ratio of chlorophyll to carotenoid absorption maximum, greatest effect on photosynthesis

500 nm~ 620nm pigment absorption rates are not high

620nm ~ 750nm (red) chlorophyll absorption rate "high" that had significant effects on photosynthesis and light cycle effects

750nm ~ 1000nm low absorption rate and stimulates cellular extension, affect the flowering and seed germination

>1000nm converted into heat

Wavelength type rich, and just and plant light synthesis and light form built of spectrum range anastomosis; spectrum wave width half width, can according to need combination get pure monochrome light and composite spectrum,; can concentrated specific wavelength of light balanced to irradiation crop; not only can regulation crop flowering and strong, and also can control strains high and plant of nutrition components; system fever less, occupied space small, can for multilayer cultivation stereo combination system, achieved has low heat load and production space miniaturization;

Sunshine is necessary for plant growth beyond the nutrition and water. But every growers know that sunlight is unable to control. Artificial sunlight is more and more recognized in the horticulture cultivation, because artificial daylight-controlled plant growth season and drastically shorten the time of plant growth.

Have the following uses:

1, as a supplementary light, at any time of the day can enhance the lighting, so that always helps the plants for photosynthesis. Especially in the winter months, you can extend the effective lighting time.

Whether in the evening or at night, can prolong and scientifically control plants need light, is not subject to any environmental change effects.

2, in the greenhouse, or plant laboratory, can substitute for natural light, to promote plant growth.

For the vast majority of growers, plant sodium lamp and metal halide lamp replaced sunshine is the best light source. Metal halide lamps are loaded with Blu-ray is suitable for early plant growth of the foliage, agro-sodium-rich red-orange light, have a positive effect on plants bearing fruit.
